Ionization SensorsThese are generally more responsive to flaming fires. They contain a small amount of radioactive material that ionizes the air between two electrically charged plates. When smoke enters the chamber, it disrupts the flow of ions, triggering the alarm.
Photoelectric SensorsThese are more effective at detecting smoldering fires—the kind that may burn for hours before bursting into flames. They use a light source and a light sensor. When smoke enters the chamber, it scatters the light, directing it onto the sensor and activating the alarm. fire alarm systems for home
Comprehensive Guide to Residential Fire Alarm Systems Residential fire alarm systems are the first line of defense against property damage and loss of life. Modern technology has evolved these systems from simple noise-makers into sophisticated networks that provide early detection and rapid response.
